Rough Road Sensor Malfunction

on 2020 Hyundai Tucson 2.4L I4 · AWD

What this code means

The PCM has detected a malfunction with the rough road sensor or its circuit. The rough road sensor tells the PCM when the vehicle is on rough terrain so it can distinguish road-induced crankshaft speed variation from actual misfires.

Symptoms

  • Check Engine Light
  • False misfire codes may set on rough roads
  • No driveability symptoms typically

Common causes

  • Faulty rough road sensor
  • Wiring issue in rough road sensor circuit
  • Sensor connector corrosion
  • ABS wheel speed sensor issue providing rough road data

Diagnostic steps

  1. Check rough road sensor signal on scan tool
  2. Inspect sensor wiring and connector
  3. Test sensor output
  4. Check if ABS wheel speed sensors are providing data

Repair notes

Replace the rough road sensor or repair wiring; false misfire codes should stop after repair.

⚠ STILL BEHIND THE PAYWALL
The 2020 Hyundai Tucson repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
